Studies on Phosphorus fractions under P × Fe interaction in Maize
Limited information is available on the impact of phosphorus and iron interaction. Therefore, a study was undertaken on sandy loam (light textured) and clay loam (heavy textured) soil in a screen house taking maize as a test crop. In both light and heavy textured soils, Saloid-P content of soil was increased up to highest level (40 mg kg-1) of P application. Application of various levels of Fe either as soil or foliar spray did not influence significantly the Saloid-P content of both type of soils. In light textured soil, application of phosphorus significantly affected the Al-P in the soil up to the highest level. Application of Fe either as soil or foliar spray did not improve Al-P fraction significantly, rather, numerically it was decreased as compared to control. There was an increase in Al-P content of heavy textured soil with increasing level of P application. The results did not show any significant differences in Al-P as a resultant of Fe application either as soil or foliar spray. Under both light and heavy textured soils, there was numerically increase in Fe-P with the increase in P level over control, while Fe application resulted in decrease in its fraction with increase in Fe level. With the increasing rate of P application in light and heavy textured soils, Ca-P fraction was also increased. Non-significant effect of Fe application either as soil or foliar spray was observed for Ca-P content. It decreased with increasing level of Fe application over their respective controls under both light and heavy textured soils. Phosphorus and Iron are found to be negatively interacting at higher level of application of iron.
An experimental comparison of meter calibration used in a photovoltaic water pumping system installed in an arid environment
Energy and water are crucial for humans in all their activities. In rural areas, irrigation is a surviving key where sustainable approaches like solar water pumping systems are required to meet this demand. One of the crucial challenges in the hydraulic field is the flow rate measurement with high accuracy. The exact estimation of the water flow rate pumped using a solar photovoltaic water pumping system is essential to evaluate the system's performance. This paper presents an analytical method to study a comparative analysis of the results of the system measurement errors. The experimental data are collected from our pumping system located in Adrar city (Algeria). The performance is analyzed using the measured water flow rate data using three different meters, one ultrasonic and two turbine meters, where a turbine meter is used as a standard meter. The test was done in May 2019.
Interactions between domestic income and Sectoral transformation: A time series analysis of carpet industry in the Union territory of Jammu and Kashmir
Jammu and Kashmir is known to the world for its cultural heritage and shares much resemblance to the Middle Eastern countries like Iran. The cultural richness of the valley is showcased through various mediums and carpet is one the main reflections of it. The study attempted to analyze the impact of domestic income, horticulture output, political conflict and population growth on the carpet industry of Jammu and Kashmir. Taking annual time series data from 1990 onwards, the autoregressive distributed lag (ARDL) model is employed to estimate the long run and short run results. The empirical results indicate that domestic income negatively affecting the output of the carpet industry both in the long run as well as in the short run. Further, some sort of structural shift from primary commodities to secondary and tertiary sectors is visible from the econometric results. It is also revealed by the results that during political upheaval and lockdowns, the carpet industry provides a lifeline to support the local employment. The paradoxical findings arise due to fact that clampdown and terror has forced the people to look for safer jobs and at the same time to be closer to their families and relatives. The horticulture activities compliment the carpet output by releasing the labor in slack seasons. The whole diagnostic testing deducts that our model is robust and statistically significant. The theoretical properties driven out of this study can be used for policy analysis.
A study on Foreign Matters Analysis in lint grade of some Egyptian Cotton Varieties and their Effect on Fiber and yarn Quality
This study was carried out to investigate the effect of the cleaning process (cleaning and without cleaning) and lint grades six grades (G/FG, G, FGF/ G, FGF, GF/FGF and GF) on fiber quality (upper half mean length m.m.), uniformity index% fiber strength g/Tex and micronair value and yarn quality – C. V%-) of some extra-long-staple cotton varieties (Giza 93, Giza87, Giza92, Giza96, and Giza88) and some long-staple cotton verities (Giza86, giza94, giza97, giza90 and Giza 95) and their interaction. Results indicated that the difference between cleaning treatments’ upper half mean length (m.m), uniformity index%, fiber strength (g/Tex), Micronair, yarn strength, and yarn and yarn evenness (C.V%) were significant at all varieties of extra-long staple. Results showed that differences between lint grades six were significant. G/FG and G grades gave the best values for all studied traits, and GF gave the worst values for all these traits. Also, results indicated that the differences between verities were significant for all studied traits. The interaction between the cleaning process and verities on yarn strength and yarn evenness (C.V%) was significant.
EVALUATION OF THE EFFICACY OF NEW HERBICIDE FOR CONTROL OF BROADLEAVED WEEDS IN WHEAT UNDER MID HILL CONDITIONS OF HIMACHAL PRADESH
Due to the absence of effective management techniques, weed infestation is one of the main biotic factors affecting wheat output and productivity. Herbicides are a crucial part of agricultural production systems because they are the quickest, cheapest, and most effective way to control weeds. Decrease in the use of herbicides without compromising yields can save production costs and environmental damage. Evaluation of herbicides and their mixtures were studied at the experimental farm of the Department of Agronomy, CSK HPKV, Palampur, to control the broad-leaf weed infestation in wheat. Findings exhibit that among the different herbicide treatments tested Halauxifen methyl Ester + Florasulam + Polyglycol recorded significantly higher growth and yield attributes of wheat which was statistically at par with Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while significantly lower growth and yield attributes of wheat was recorded in weedy check treatment. Higher yield (straw and grain) and weed control efficiency of wheat was recorded in Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while lower grain yield, straw yield and weed control efficiency was recorded in weedy check. Hence, highest gross returns (134.3 × 103 INR ha-1), net returns (91.4 × 103 INR ha-1) and B: C ratio (2.13) were obtained from Halauxifen-methyl + florasulam + carfentrazone + surfactant 10.21 + 20 g a.i. ha 1 treatment.
